[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Referring to Figures 1, 5, and 6, one embodiment of this utility model provides a safety plastic bag, comprising a square plastic bag 1. The square plastic bag 1 has a regular shape, facilitating placement and stacking in various scenarios. An outer layer 3 is provided on the inner wall of the square plastic bag 1 to ensure the overall shape stability of the plastic bag and prevent excessive deformation during use. A barrier layer 4 is provided on the outer wall of the outer layer 3, which has good barrier properties and can effectively prevent external oxygen and moisture from entering the plastic bag. An antibacterial layer 5 is provided on the outer wall of the barrier layer 4, preventing bacteria from growing on the surface of the plastic bag. To prevent the growth and spread of bacteria, the outer wall of the antibacterial layer 5 is provided with a waterproof inner layer 6. The waterproof inner layer 6 has excellent waterproof performance, preventing external moisture from penetrating into the interior of the plastic bag. The outer wall of the waterproof inner layer 6 is provided with a reinforcing layer 7. The reinforcing layer 7 enhances the overall strength and toughness of the plastic bag, making it less prone to breakage and damage when subjected to certain tensile, compressive, and impact forces. The bottom of the inner wall of the square plastic bag 1 is fixedly connected with a thickening layer 8. The thickening layer 8 can increase the thickness and strength of the bottom, improving the load-bearing capacity of the bottom. The outer wall of the thickening layer 8 is fixedly connected with a protective layer 9. The top left and right sides of the outer wall of the square plastic bag 1 are provided with protective mechanisms 2.

[0041] Specifically, the square plastic bag 1 serves as the main body, with layers stacked from the inside out: an outer layer 3, a barrier layer 4, an antibacterial layer 5, a waterproof inner layer 6, and a reinforcing layer 7. A thickened layer 8 and a protective layer 9 are also added at the bottom. These layers work together to comprehensively ensure the safety and quality of the items inside the bag from multiple dimensions, including barrier, antibacterial, waterproof, reinforcement, and protection, meeting the needs of different usage scenarios.

[0042] Referring to Figures 2, 3, and 4, the protective mechanism 2 includes two zippers 201. The adjacent sides of the two zippers 201 are fixedly connected to the top left and right sides of the square plastic bag 1, respectively. The square plastic bag 1 provides a convenient opening and closing method. Pull rings 202 are slidably connected to the top of the outer walls of both zippers 201, providing a point of leverage for the user to easily operate the zippers 201. Two dustproof cloths 203 are fixedly connected to the opposite sides of the two zippers 201, respectively. The main function of the dustproof cloths 203 is to prevent dust and impurities from entering the plastic bag. Inside the bag, a button 204 is fixedly connected to the right side of the outer wall of the right dustproof cloth 203, and a button groove 205 is fixedly connected to the left side of the outer wall of the left dustproof cloth 203. The inner wall of the button groove 205 engages with the outer wall of the button 204. When the button 204 is inserted into the button groove 205, the two can be tightly engaged, further strengthening the connection between the dustproof cloths 203. This engaging method is not only simple and convenient to operate, but also has good stability, ensuring that the dustproof cloth 203 will not easily separate during use, thus better playing its dustproof role.

[0043] Specifically, in use, the pull ring 202 opens and closes the zipper 201 to access items. After closing the zipper 201, the dustproof cloth 203 covers the gaps in the zipper 201 to block dust. Then, the button 204 engages with the button slot 205 to enhance the overall protective performance, protecting the items inside the bag from dust and impurities in all directions.

[0044] Referring to Figures 2, 4, and 6, the outer wall of the square plastic bag 1 has multiple connecting grooves 10 on the front and back sides of the top. Connecting pieces 11 are fixedly connected to the inner walls of the multiple connecting grooves 10, acting as connecting bridges. Hanging rings 12 are fixedly connected to the front and back sides of the top of the square plastic bag 1. Connecting pieces 13 are fixedly connected to the bottom left and right sides of the two hanging rings 12. The hanging rings 12 are fixed to the front and back sides of the top of the square plastic bag 1, providing a convenient way for the user to carry it. Multiple locking posts 14 are fixedly connected to the rear top of the front hanging ring 12, and multiple locking holes 15 are opened on the front top of the rear hanging ring 12. The inner walls of the multiple locking holes 15 engage with the outer walls of the multiple locking posts 14. The design of the multiple locking posts 14 increases the stability and firmness of the connection, making it less prone to loosening during the connection process.

[0045] Specifically, the connecting piece 11 can be used as a connecting component to cooperate with a specific external device to meet different usage scenarios. When multiple plastic bags are stacked or hung, inserting the locking post 14 into the locking hole 15 can tightly connect the front and rear hanging rings 12, preventing the plastic bags from shaking or slipping and enhancing stability.

[0046] Referring to Figures 2, 5, and 6, the inner wall of the square plastic bag 1 has connecting grooves 2 and 16 on both the front and back sides. A diaphragm 17 is fixedly connected between adjacent inner walls of the two connecting grooves 2 and 16. The connecting grooves 2 and 16, located on the front and back sides of the inner wall of the square plastic bag 1, provide a specific position and structural basis for installing other components. The diaphragm 17 is fixed inside the square plastic bag 1 through the connecting grooves 2 and 16, dividing the internal space of the plastic bag in two. Storage bags 18 are fixedly connected to the left and right sides of the inner wall of the square plastic bag 1. The outer walls of both storage bags 18 are rounded. The storage bags 18 are fixed to the left and right sides of the inner wall of the square plastic bag 1, providing users with additional storage space. Multiple connecting grooves 10 are equidistantly fixed to the front and back sides of the outer wall of the square plastic bag 1. The outer walls of multiple connecting grooves 10 are square, capable of withstanding certain external forces without easily deforming, further improving the strength of the connection.

[0047] Specifically, the interior of the plastic bag is divided into two independent spaces for easy classification and storage of items, avoiding mutual compression and cross-contamination of odors, such as food and daily necessities. The outer wall adopts a smooth design to avoid scratching other items inside the bag and to protect the surface of items such as electronic products and jewelry. The regular distribution and specific shape allow the connecting slot 10 to accurately dock with external equipment with a compatible structure.

[0048] Working Principle: A square plastic bag 1 serves as the overall structure, providing storage space. The outer layer 3 of the inner wall provides basic support for the subsequent multi-layered structure, maintaining the stability of the plastic bag's shape and preventing easy deformation due to external impacts. The barrier layer 4 on the outer wall of the outer layer 3, with its excellent barrier properties, blocks the penetration of oxygen, moisture, and liquids, preventing the contents from oxidizing or becoming damp and extending their shelf life. The antibacterial layer 5 on the outside of the barrier layer 4 inhibits the growth and reproduction of bacteria and mold, effectively preventing microbial contamination of the contents and ensuring hygiene and safety. It is especially suitable for packaging food and medicine. For items with high hygiene requirements, the waterproof inner layer 6 outside the antibacterial layer 5 can resist the intrusion of external moisture and prevent the items inside the bag from being damaged by contact with water, providing reliable protection for water-sensitive items. The reinforcing layer 7 outside the waterproof inner layer 6 increases the strength and toughness of the plastic bag, reducing the risk of it being damaged by pulling and squeezing during use, and enhancing its durability. The thickened layer 8 at the bottom of the inner wall of the square plastic bag 1 increases the thickness and strength of the bottom, improves the load-bearing capacity, and prevents the bottom from breaking due to the pressure of heavy objects. The protective layer 9 on the outer wall of the thickened layer 8 can resist external scratches and collisions, preventing damage to the items at the bottom.

[0049] Furthermore, when it is necessary to open or close the plastic bag, the user can pull the pull ring 202 to slide the zipper 201, which is fixedly connected to the top left and right sides of the square plastic bag 1, to achieve convenient opening and closing operation. The dustproof cloth 203 fixed on the far side of the zipper 201 can cover the gap of the zipper 201 after the zipper 201 is closed. When in use, the button 204 on the right dustproof cloth 203 is engaged with the button groove 205 on the left dustproof cloth 203 to further enhance the sealing performance, prevent dust and impurities from entering the bag from the gap of the zipper 201, keep the items inside the bag clean, and improve the overall protective performance to ensure that the items are not contaminated by the outside world during storage and carrying.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
